A study of unbound states in 17 C by means of one-neutron knockout from a fast moving 18 C beam at an energy of 245 MeV/nucleon on a carbon target was performed at the RIKEN-RIBF laboratory utilizing SAMURAI. The energy spectrum of unbound 17 C constructed from momentum vectors of the forward going beam velocity 16 C fragment and neutron covered an energy range of the decay neutron below about 6 MeV in the center of mass of 17 C*. The relative energy Erel spectrum was characterized by two resonances at about 1.92 and 3.24 MeV in E rel and a possible multiplet at around E rel ~ 0.7 MeV. Momentum distributions of the knockout residue for the E rel = 1.92 and 3.24-MeV states well matched to those of p-wave neutron removal, providing a model independent confirmation of negative parity assignments for these states. The proposed level scheme of 17 C was compared with a range of different shell-model predictions; it turned out that the YSOX shell-model interaction, employing the monopole-based universal interaction for the cross-shell two-body matrix elements and incorporating larger ?! excitations, gave a consistent account of it, including the locations of the 1=2 1 - and 3=2 1 - cross-shell states.
